Answer:5/2

Step-by-step explanation: Slope is rise (how far up or down) over run (how far left to right. Look for points where the line crosses a perfect grid line intersection. The graph goes up to 50 and right 20 (started at 10 and ended at 30). The rise/run is 50/20 or 5/2 reduced.

first, find two places on the line that intersects the grid boxed neatly. This occurs at (10 , 0) and (30 , 50).

slope = change in rise / change in run

slope = change in y / change in x

slope = ( 0 - 50) / (10 - 30)

slope = -50/-20

slope = 50/20

slope = 5/2

The transformation g(x) = -f(x) converts the graph of

f(x) = 8x^2 - 7 into the graph of g(x) = -8x^2 + 7.

What is transformation of graph?

The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation. In particular, the change of algebraic equations, it is a typical kind of algebraic problem.

Given:  f(x) = 8x^2 - 7.

We have to find what kind of transformation converts the graph

f(x) = 8x^2 - 7 into the graph of g(x) = -8x^2 + 7.

Let,

f(x) = 8x^2 - 7

Multiply both sides by -1.

⇒ -f(x) = -8x^2 - (-7)

  - f(x) = -8x^2 + 7

Since g(x) = -8x^2 + 7

⇒    -f(x) = g(x)

⇒    g(x) = -f(x)

Therefore, the transformation g(x) = -f(x) converts the graph of

f(x) = 8x^2 - 7 into the graph of g(x) = -8x^2 + 7.

The flower arrangements with $200 has lower unit price than the flower arrangements with $70 unit price.

The average price of a product is calculated by dividing the total sales income by the total number of units sold. When a same product is supplied in variants, such as bottle sizes, managers must define "similar" units. Average prices can be estimated by dividing distinct unit selling prices by the percentage of unit sales (mix) for each product variant. When we utilize a standard rather than an actual mix of sizes and product variations, the result is price per statistical unit. Statistical units are sometimes known as analogous units.

Unit price for 15 flower arrangements for $200 is,

200/15=13.33

Unit price for 5 flower arrangements for $70 is,

70/5=14

Therefore, 14>13.33

So, the flower arrangements with $200 has lower unit price than the flower arrangements with $70 unit price.

9. The plane's speed would be of 340 and 350 miles per hour.

10. She runs the downhill portion of the course at a rate of 10 miles per hour.

11. The total time would be of 24 minutes.

Velocity is distance divided by time, hence the equations is:

v = d/t.

For the first plane, the velocity and the distances are given by:

v = v + 10, d = 495.

Hence:

v + 10 = 495/t

t = 495/v + 10

For the second plane, the velocity and the distance are:

v = v, d = 510.

Hence:

v = 510/t

t = 510/v

The time is equal, hence the velocity of the slower plane is obtained as follows:

495/v + 10 = 510/v

Applying cross multiplication:

510v + 5100 = 495v

15v = 5100

v = 5100/15

v = 340 mph

For the runner, we have two parts, as follows:

Hence the equations are given as follows:

From the first equation, we have that:

v = 5 + 3/t.

Replacing in the second, we have that:

5 + 3/t = 4/(1 - t)

(5t + 3)/t = 4/(1 - t)

Applying cross multiplication, we have that:

(5t + 3)(1 - t) = 4t

-5t² + 2t + 3 = 4t

5t² + 2t - 3 = 0.

The positive solution, as time is a positive measure, of the quadratic equation is given by:

t = 0.6.

Hence the velocity of the downhill part is given by:

v = 4/(1 - t) = 4/0.4 = 10 miles per hour.

The together rate is the sum of each separate rates.

The rates in this problem are given as follows:

Hence:

1/x = 1/30 + 1/120

1/x = 5/120

x = 120/5

x = 24 minutes.

The equation that represents the number of weeks that is needed to baby sit to buy gaming chair is 35.5w + 136.45 = 455.95; w = 9  , the correct option is (b) .

In the question ,

it is given that

the cost of the gaming chair = $455.95

amount of money already saved for the gaming chair = $136.45

amount of money earned by baby sitting each week = $35.50 .

let the number of weeks required to baby sit is " w  " .

the equation can be represented by

cost of chair = money saved + money earned in w weeks

Substituting the values from above ,

we get

455.95 = 136.45 + 35.5w

On solving further ,

136.45 + 35.5w = 455.95

35.52w = 455.95 - 136.45

35.52w = 319.5

w = 319.5 / 35.52

w = 8.99

w ≈ 9

the number of weeks = 9

Therefore , The equation that represents the number of weeks that is needed to baby sit to buy gaming chair is  35.5w + 136.45 = 455.95; w = 9  .

Jeffry will get greatest total revenue when he charges the lemonade $1.40

Given,

The price per servings of lemonade = $0.80

Number of servings = 200

For each $0.10 that he adds to the price, Jeffrey will lose 10 customers.

We have to find the greatest total revenue he got.

Lets check.

0.80 x 200 = $160

0.90 x 190 = $171

1.00 x 180 = $180

After a small search on the internet, I've found that this question asks for the constant of proportionality.

Remember that a proportional relation is of the form:

y = k*x

Where k is the constant of proportionality, and x and y are the variables.

Here the relation is:

m = 3*b

Answer:

1. x² 2. x

Step-by-step explanation:

For these problems, there actually pretty easy. What you do is the numbers like x2 are x times 2. So, like if x is 3, it would be equal to 6 because 3 times 2 is 6. Easy, right?

But this time, it is asking you for GCF. It's harder, but it will be easy after you understand it.

#1

So, it organizes the equation. So x2 gets simplified to x times 2. x*2 is double the amount. x + y and x - z. Take the x's that is 2 x's. So x2. Then y and z which are unknown has the value left. And 1 more thing. Since there is no operation, it turns in to times/multiply. Please don't ask why. Ask it in a new question. So you can cross them off and multiply x2 with y times z. The equation now is basically x2 y times z). y times z. Again, the numbers are unknown. So you need to count them as zero. Add 2 zero's together is 0. Add x2 to 0. Which is x2.

You can now do problem 2 by yourself after you read the explanation. Remember, your answer isn't always like this type of explanation. Some one's work, try this for all your problems related. See if it works.

Therefore, the GCF of x2(x + y) (x - z) is x2
